CMB spectral distortions constraints on primordial black holes, cosmic strings and long lived unstable particles revisited
Sandeep Kumar Acharya, Rishi Khatri
We calculate the spectral distortions from Hawking evaporation of primordial black holes before the epoch of recombination, taking into account emission of all standard model parti…

CMB anisotropy and BBN constraints on pre-recombination decay of dark matter to visible particles
Sandeep Kumar Acharya, Rishi Khatri
Injection of high energy electromagnetic particles around the recombination epoch can modify the standard recombination history and therefore the CMB anisotropy power spectrum. Pre…

New CMB spectral distortion constraints on decaying dark matter with full evolution of electromagnetic cascades before recombination
Sandeep Kumar Acharya, Rishi Khatri
Current constraints on energy injection in the form of energetic particles before the epoch of recombination using CMB spectral distortions assume that all energy goes into and…
